A map of the world with vertical lines marking the time zones from UTC-12 to UTC+12. It has a legend:
Wrong Time
"Natural time zones" are 15° in longitude. Land in red observes a time other than the zone it lies within. Smaller islands depict their 12 nautical mile territorial sea, for visual effect. In some cases this includes a state's archipelagic waters.

"wrong". technically it's entirely made up. you can write whatever number you want on the scale where the sun hits the zenith as long as all people nearby can agree to it.
Yeah, methinks a gradient would have been better instead of a solid demarcation
